The standard error of the mean is the standard deviation which is 6.50
Answer:
You know you could just look up every single one of these
Step-by-step explanation:
If this is algebra, then you want to isolate the t. you need to subtract 1800 on both sides so then the expression would be 16t2= -1800. now you want to divide 16. t2= -112.5 then divide by 2 t= -56.25
Answer:
The required equation in standard form is 
Step-by-step explanation:
The equation of a circle with center (h,k) an radius, r units is given by the formula;

The given circle has center (-2,0) and radius squared can be calculated from the given area, which is 


We substitute these values into the formula to obtain;

We simplify to get;
